Question

what is Mirror mechanism formula

Answer 1

MIRROR FORMULA;

================

Mirror formula is relationship that combines image distance ,object distance and focal length of the mirror .

Expression for mirror formula is

_______________________________

1/u+1/v=1/f

______________

Here u=object distance as measured from pole of the mirror

V=image distance

f being the focal length of the mirror.

The values of all these parameters should be used by taking into consideration the following signconventions in measurement of distances in case of mirrors .

1 )All distances are measured from pole of mirror

2) Distances measured in the direction of light are taken as positive and those measured opposite to it are taken as negative .
